I would suggest higher flow in that area, or a tough coral(LPS) to contain the growth of them. I like the way it looks when overgrown, but perhaps thats just me.
I have a 6 bulb T5 about 1/3 way up in a 75g. 2 10k white 3 actinc 1 bulb I can't remember. Flow is light with 2 koralia evo powerheads. They don't like high flow and don't require intense lighting.
